(in more-depth)

Charlie Morningstar, Demon Queen of Hell, glared at the stallion before her. His sleek black coat glistened in the fiery light of the underworld, but it was his obedient demeanor that truly pleased her.

After centuries of bitter rivalry with the angelic host and a particularly vicious fight with the insufferable Vaggie, Charlie had stumbled into an unexpected alliance. Alastor, a powerful demon, had offered her a deal—a binding of their souls, ensuring eternal togetherness. Charlie, in her rage and desperation, had accepted.

But once the deal was sealed, the power dynamic flipped on its head. Charlie discovered she could control Alastor's every thought, bending him to her will. It was both intoxicating and terrifying.

She leaned in close, her crimson eyes locked on his. "Oh, it's heat-time, eh?"

Alastor whinnied, his muscular body shuddering as an intense arousal washed over him. Charlie smirked, knowing the control she wielded. With a flick of her fingers, she sent the stallion stumbling forward, his cock hardening to an impressive size.

He collapsed to his knees before her, a submissive creature, eager to please his demonic mistress. Charlie caressed his mane, reveling in the power she held over this formerly proud demon. "You'll ride under my will now, pet," she purred, "and obey my every whim."

Alastor nuzzled her hand, his mind already conforming to her desires. Together, they would conquer the realms of heaven and hell, their bond unbreakable. Charlie Morningstar, Demon Queen, had finally found the perfect partner in her eternal games. And Alastor, once high and mighty in the demonic world, now eagerly followed the command of his lust-drunk, wicked mistress—his soul bound to hers forevermore but hey that's what they wished for right.
